Does anyone have the ECU Pinout's for an s13 blacktop??I got an Apex'i Multichecker a while ago and haven'tbeen able too hook it up because I lost the link I hadfor the pinouts. I seem to recall a webpage that hada numbered diagram of the pins and then a list of whateach number was the signal for.

The multichecker I have has 10 colored wires comingfrom the control box, and so far this is what I havegathered.

Red - 12V sourceBlack - GroundOrange - Injector SignalBlue - Crank (120, 180 degree signal)Pink - ( No.1 ignition signal)Brown - ( Crank 1 degree signal)White - ( Airflow signal)Grey - ( Limiter cancel signal)Green - (Vehicle Speed Sensor)Light Blue - ( ???? I have no idea what this wireconnects to)

if anyone has an link to the ECU pinouts, or has amultichecker installed on their SR and can tell mewhat color wire matches to which ECU wire or pin Iwould greatly appreciate it.

Also, is it a good idea to tap into the 12V supply &ground going into the ECU at the pin, or should I tapinto a 12V somewhere else.

Thanks, Cliff

I just finished the install so i'll put this here as a reference:

Red - 12V source =========>SR ECU PIN#36Black - Ground ===========> PIN#39Orange - Injector Signal ====> PIN#101Blue - Crank (180 degree signal) ===> PIN#30Pink - ( No.1 ignition signal)=======> PIN#1Brown - ( Crank 1 degree signal)===> PIN#31White - ( Airflow signal)=========> PIN#16Grey - ( Limiter cancel signal)Green - (Vehicle Speed Sensor) ===> PIN#32

for speed cut cancellation hook up grey and green wires in serieswith wire from pin #32

Light Blue - not used

Hope this helps someone in the future
